Seattle Washington Info needed ?

Anyone have ideas as what to see while in Seattle, I know the Space Needle and the Fish Market ?
My wife and I will be out there attending a wedding, so we just decided to make a vacation out of it.
Need Ideas ? Thanks

I have been to Seattle a few times but didn't stay in the city much. Mt. St. Helens is a good place to go and is about 90-100 miles south of there. Well worth the drive. Just hope it is clear. The Columbia River is also pretty cool but will be a far drive.

MT Ranier is good, Pike Place market is worth the visit. I found the Space Needle to be a disappointment. Great to see it on the skyline but the actual tour is expensive and it surrounded by a small amusement park

Lots of good places to get fresh seafood there.

I would reccomend this one.

The Athenian Seafood Restaurant and Bar

A scene from Sleepless in Seattle was filmed there.

several good breweries and excellent coffee at several shops (maybe even starbucks) if you are into either

Thanks Justin... They are added to the list !
